On Plasticity and Damage Evolution During Sheet Metal Forming
Based on experimental considerations, the proposed damage law considers that the growth of micro-voids results in a non-linear damage accumulation with plastic deformation. This paper presents a non-linear Continuum Damage Mechanics (C.D.M.) model for the prediction of ductile plastic damage analysis under large deformations such as in the case of metal forming. The dependence of the damage on temperature, strain rate and microstructure are discussed.
